Bosch HMV3052U Installation Instruction

Wall venting installation only: Preparing rear wall
For wall venting installation you need to cut out an

opening on the rear wall.

CAUTION

If exhaust adaptor is positioned outside consider

recommended dimensions, otherwise grease-laden

air will discharge into house structure.

Mark the centerline (See Attaching the mounting plate

to the wall) 3\8" (10 mm) down from the top of the

mounting plate.

Using measuring tape, measure out 6" (152 mm) on

both sides of the centerline, and mark.

Measure down 4" (102 mm) from the mark made in

Step 1, and mark.

Using a straight edge, draw the 2 horizontal level lines

through the marks made in Steps 1 and 3.

Draw the 2 vertical plumb lines down from the marks

made in Step 2 to complete the 12" x 4" (304 x 102

mm) rectangle. This is the venting cutout area.
The 12" x 4" (305 x 102 mm) cutout area must align

with the wall damper vent (where the damper

assembly will be installed) on the back of the

microwave oven.

Note: Cutout must be free of any obstruction (e.g.

wiring, pipes, etc.) so that the vent fits properly, and

the damper hinge opens fully and swings freely.

Using a saber or keyhole saw, cut out this area

through the rear wall.

Mounting the microwave oven

Notes

▯

If the bottom of the upper cabinet is recessed or has

front overhang, you will need to prepare 2" x 2" (51

mm x 51 mm - depth equivalent to cabinet recess or

overhang) filler blocks to provide additional support for

the bolts:

▯

mark the center of each filler block and drill a 3\8"

(9,5 mm) diameter hole

▯

align filler blocks over the three openings on top of

the microwave oven and attach with masking tape

▯

Use at least two people to install the microwave oven.

Do not grip or use handle during the installation.

▯

When mounting the microwave oven, thread power

cord through hole in bottom of top cabinet. Keep the

cord tight and do not pinch it, especially when

mounting flush to bottom of cabinet. Do not pull the

cord to lift the oven.

Lift the microwave, tilt it forward, and hook slots at

back bottom edge onto four lower tabs of the

mounting plate.

Rotate the front of the oven up against cabinet bottom.

Insert a self-aligning screw (item A) through top center

cabinet hole. Temporarily secure the oven by turning

the screw at least two full turns after the threads have

engaged.
